MAX4315

The MAX4310MAX4315 single-supply mux-amps com- bine high-speed operation, low-glitch switching, and excel- lent video specifications. The six products in this family are differentiated by the number of multiplexer inputs and the gain configuration. The MAX4310/MAX4311/MAX4312 inte-grate 2-/4-/8-channel multiplexers, respectively, with an adjustable gain amplifier optimized for unity-gain stability. The MAX4313/MAX4314/MAX4315 integrate 2-/4-/8-chan- nel multiplexers, respectively, with a +2V/V fixed-gain amplifier.

All devices have 40ns channel switching time and low 10mVp-p switching transients, makinthem ideal for video-switching applications. They operate from a sin- gle +4V to +10.5V supply, or from dual supplies of ±2V to ±5.25V, and they feature  Rail-to-Rail ® outputs and an input common-mode voltage range that extends to the negative supply rail.

The MAX4310/MAX4311/MAX4312 have a -3dB bandwidthof 280MHz/345MHz/265MHz and up to a 460V/µs slew rate.The MAX4313/MAX4314/MAX4315, with 150MHz/127MHz/ 97MHz -3dB bandwidths up to 540V/µs slew rate, and a fixed gain of +2V/V, are ideally suited for driving back- terminated cables. Quiescent supply current is as low as6.1mA, while low-power shutdown mode reduces supply current to as low as 560µA and places the outputs in a high-impedance state. The MAX4310MAX4315's internal amplifiers maintain an open-loop output impedance of only 8Ω over the full output voltage range, minimizing the gain error and bandwidth changes under loads typical of most rail-to-rail amplifiers. With differential gain and phase errors of 0.06% and 0.08°, respectively, these devices are ideal for broadcast vidapplications.
